Pale Evening Dun - SpinnerThe spinners have two tails that are about the same length as the body. Like most spinners the wings are translucent or clear. The spinner fall usually occurs in the late afternoon or evening over the same riffles the mayflies hatched in. The females touch the surface of the water to deposit their eggs. When they are finished, they fall spent on the water. Trout eat them when they are depositing their eggs and after they fall spent. These spinners will collect in the current seams and end up in eddies and calm pockets along the banks and behind boulders and rocks. They can also end up in the heads of pools in the riffles and runs terminate there.

Presentation:When they are depositing their eggs you want to present you spinner imitation where you see this activity occurring. This may not be possible in some cases because they may do so in the evenings.

It is best to fish to individual fish if you can spot them feeding on the spinners. If you loose tract of the fly you may try moving it very slightly - just enough to see the wake the fly makes. Just make sure you do this before the fly gets near the fish you are trying to catch.

Present the spent spinner imitation below the riffles at the head of pools or runs. It is very difficult at the normal late time of day to see the spinners or your spinner imitation. You should concentrate on watching the leader at the point it connects to the end of the fly line for any stops or changes in movement. The trout just sip the spinners and make only a slight disturbance on the surface, so it is not easy to see them sipping in the spent spinners.
